Emax

I have an Emax HD with a faulty PSU and 7 broken keys.  I also have an Emax II with a faulty disk drive.

Was wondering if it would possible to swap the PSU from the Emax II into Emax I as well as the entire keybed?

I would prefer using the analog filter of the Emax I; however, if this is not possible then is it possible to swap out the HD and the Floppy drive from the Emax I and pop it into the Emax II?

Thanks.
